To all It'll/0111 it may (rm/c171.-

Be it known that we, FREDERICK .b. ROB- INSUN and JOHN McCain), citizensof the United States, residing at theyenne, in the county of Laramie andState ol Wyoming, have invented a new and ust t'ul 'lraclr-banrb ingApparatus, ot which the following is a specification.

This invention rclatts to means carried by locomotives or traction-carsfor delivering sand to the tracks whenever deemed desirable to preventslipping of the wheels.

The principal object is to provide simple mechanism of a novel naturewhich will insure the delivery of sand, is readily adjustable to securethe proper llow oi the ntaterial, is not apt to become clogged orinoperative, but may be made to clean itself, and yet is so constructrdthat the interior parts are readily accessible whenever it becomesnecessary to examine or repair the same.

The preferred form of construction is illustrated in the accompanyingdrawings, Wherein- Figure 1 is a side elevation of a )ortion of alocomotive, showing the novel sanding mechanism applied thereto. Fig. 2an end elevation of a portion thereof, shown on an cnlargi scale. Fig. 3is a side elevation of the same. Fig. 4 is atop plan view. Fig. 5 is asectional view on the line 5 5 of Fig. 4. Fig. 6 is a sectional view onthe line 6 (5 oi Fig. 4.

Similar reference-numerals designate corresponding parts in all thefigures of the drawings.

Whilethe invention in the present case is shown in connection with alocomotive. it is to be understood that it is not limited thereto, butis capable of successful use upon cars of any character having amotive-thud supply.

in the present embodiment the sand-box oi the locomotive is designated7, and leading therefrom is a pipe 8, connected to the upper end of acasing t). This casing t) is divided into spaced depending legs it),each having iippositelywmending nipples it and t2. The lower ends oi thelegs are closed by detachable plugs 13, threaded ihercinto.Sand-conducting pipes 14 (.Xttlitl l'rom the nipples 11 and have theirdischarge ends t5 arranged, respectively, in front and in rear ot' thedriving-wheels oi the locomotive.

Plugs lti are threaded into the nipples 12, and screwed into the innerends of these i plugs are nozzles 17, that project across the legstoward the nipplesll, terminating short oi" the same. Loch-nuts its arethreaded upon the exterior portions of the plugs and are arranged to jamagainst the outer end ol the nipples t2. i\l tive-tlui l-conductingpipcs' it), connected with any suitable source ol'supply through themedium oi'- a common pipe ill, have 'alves 2] located at their juncturewith the pipe 20. The other ends of these pipes are connected bybonnet-nuts 22 to couplings that are threaded into the outer ends of theplugs 16. Thus motive lluid supplied to the nozzles 17. The VOltime oithe llowis controlled, however, byturning valves or plugs 24, that arejournalcd in the couplings 23, and have angularly-disposed passage-ways25 and 26 thcrethrough, said passage-ways being of ditlerent diameters.The upper ends of the valves are provided with crossed notches 27 and 28ot ditl'erent sizes to correspond to the passage-ways, and thusconstitute indicators therefor.

Under ordinary conditions the smaller passage-ways 26 are in line withthe bores through the motive-tluid-supply conduit, and consequently thelarger passage-ways are cutout. It, therefore. motive tluid is ad mittedto either of the conduits 19, it will be projected through the nozzle17, connected to such conduit, and the sand located within the casingwill be expelled therefrom through the delivery-pipe 1st. hould thepassageway 25 become clogged by the accumulation of sand therein underordinary conditions, if the valve is reversed or given a hall-turn thepassage-way will be cleaned automatically. for the l'orm'er dischargeend thereof will then become the inlet end. ll.ho\\'evcr, this will notetl'ect the desired cl ansing action, a quarter-turp of the valve willbring the larger passage-way into line with the bore through the nipple,and a greater volume of air can then tlow through the nozzle. Thus twodil'- t'crcntpressures can be secured, and, more over, the nozzle can bereadily adjusted toward and from the inlet. end at the sand-com ductingpipe H by screwing the plug lti into or out ol the casing, being readilyheld by the jam-nut 1h. it at. any time it becomes desirable ornecessary to gain access to the interior ot the casing, it. is onlynecessary to remove either or both of the plugs 15 From the foregoing itis thought. that the construction, operation, and many advan tagesvofthe herein-described invention vvill be apparent to those skilled in theart Without further description, and it will be under stood that variouschanges in the size, shape, 1

proportion, and minor details of cons traction may be resorted towithout departing the spirit or sacrificing any of the advantages of theinvention.

Having thus fully described our invention, What We claim as new, anddesire to secure by Letters Patent, is

1. In sanding apparatus of the character set forth, the combination witha casing having an upper sand-inlet and an oil'set sanddischarge, of amotivdluid conduit, a coupling LllIGCtlil' connecting the conduit andcasing on the side opposite the sand-discharge, and a reversiblecontrolling-valve located in the coupling directly adjacent to thecasing, said valve having a iluid-conihicting passage-way therethrongh,either end of which may be made the inlet of said passage-way byreversing the valve.

2. In sanding apparatus of the character set forth, the combination witha sand-conduit, oi' motivedlnirl-conducting means, con nections betweenthe conducting means and conduit, including a coupling having an in lotand an outlet, a rotatable controllingvalve located in the conduit and.having pas sage-Ways oi" dill'eren t diameters therethroug that aremovable into allnenient with the in,- let and outlet of the coupling,both ends of each passage-Way being movable into association 'With saidinlet'ot' the coupling to secure the passage of the motive fluid inopposite directions through each passage-Way.

3. In a sanding apparatus of the character set forth, the combinationwith a sand-conduit, 0t motivedluid-conrhtoting means, connectionsbetween the cond cting means and conduit, including a coiipling havingan inlet and an outlet, a rotatable controllingvalve located in theconduit and having anmlarlv-rlisposed passage-ways ol diil'erentiameters theretl'irough that are movable into alinement with the inletand outlet oi the coupling, both ends of each passage-way being movableinto association with said inlet of the coupling to secure the passageof the motive fluid in opposite directions through each passage-way.

4. In sanding apparatnsot the character set forth, the combination witha casing having a sand-outlet, and a sand-inlet,
